Please help, I'm at the end of my tether, my 21 year old daughter who will not wear a seatbelt either driving or as a passenger. She was always brought up to wear it and everyone else in the family always wears one. I think it's a sensory thing as she has always been very difficult about changing clothes or dealing with zips and labels etc but if she is going to drive a car, she has to wear it. It's quite unusual for me to be in a car with her anymore but every time recently I have been, I've had to tell her to put it on. I know she goes straight back to not wearing one when I'm not there. I've resorted to threatening to call the police on her myself but short of taking her keys off her I don't know what to do. I'm hoping I can show her this and she can realise how reckless and stupid she's being. Please, if any of you have any pearls of wisdom to share about dealing with a stubborn, know it all daughter, I'd be so grateful.
